Application January 24, 1948, Serial No. 4,089

This invention relates to a container closure.

device. The general object of the invention is to provide an improved closure device for a container and wherein the closure device includes a recess for a medicinal tablet and sealing means therefor and wherein novel means is provided for causing release of the sealing means.

A more specific object of the invention is to provide a closure device including a novel inner member.

Another object of the invention is to provide a closure device including a novel outer member.

An additional object of the invention is to provide a closure device including novel inner and outer closure members.

Aiurther object of the invention is to provide a closure device including a novel diaphragm.

ther objects and advantages of the invention will be apparent from the following description taken in connection with the accompanying drawings, wherein:

Fig. 1 is a central, sectional view showing a container closure device embodying the features of my invention;

Fig. 2 is a view similar to Fig. 1 showing the closure in another position.

Referring to the drawing by reference characters, I have shown my invention as embodied in a closure device which is indicated generally at [0. As shown the closure device is arranged on a bottle I l. The bottle has a neck I2 which includes an outwardly directed groove l3.

My closure device consists of an inner member I d and an outer member indicated generallyat H5. The inner member includes a sleeve l6 which has an integral flange ll resting upon the end I8 of the bottle. A sealing band I9, which may be made of metal or plastic, engages the flange II and the upper wall 20 of the groove I3 to hold the parts in place.

The outer member l has a top or body 2| which has a downwardly directed integral skirt 22 there-' on. The skirt has an enlarged flange 23 at the lower end. The flange 23 is removably received in the groove i3 so that normally the parts occupy the position shown in Fig. 1. The body 2| and skirt 22 are preferably made of a good gradesoft, resilient rubber and the body includes a depending, integral, tapering stem member 25 which is made of rubber which cures harder than the rubber of which the body 2| is made so that the member 25 does not flex readily and therefore does not bend when the closure is operated, as will be later described.

The inner member I4 is made of resilient, elas- 1 Claim. (Cl. 128-272) tic rubber and the sleeve [6 forms an axial cavity 38. A groove 3| is arranged in the lower end of the cavity wall. In this groove 3! I seat a seal which is in the nature of a disc 32, which isheld in place by the resiliency of the sleeve member IS. The upper end of the cavity 30 is closed by a diaphragm in the form of 9. depending cup-shaped member indicated generally at 33, which is integral with the inner member and which includes a depending elastic wall or skirt 34 and an end wall '35. Between the wall 35 and the disc 32 I arrange a medicinal tablet 36 which is adapted to be discharged into a vehicle 37 in the bottle II.

The stem member 25 has a lower end 40 which normally is disposed adjacent to the wall 35. When the body 2| of the outer member is depressed to the position shown in Fig. 2, the elastic wall 34 will be stretched as shown in Fig. 2, thus allowing the parts to be moved to the position shown to force out and release the disc 32 and allow the medicinal tablet 36 to .drop into the vehicle. The freshly prepared solution is then ready for use, and by removing the outer member l5 the operator may insert a hypodermic needle through the end wall 35 and withdraw the desired amount of liquid from the bot tle without any chance of the contents becoming contaminated.

The disc 32 is inert in the solution and does not contaminate the solution.

In the present application, Ser. No. 4,089, filed January 24, 1948, the claim is directed to the main and outer closures, wherein the main closure includes a cupped diaphragm portion and the outer closure includes a stem which engages the cupped portion to cause release of a sealing disc. 7

In applicants copending application Ser. No. 4,193, filed January 24, l948, the claim is directed to the closure which includes a corrugated diaphragm engageable by a releasing stem carried by an auxiliary closure. 7 V

In copending application Ser. No. 791,429, filed December 12, 1947, the claims are directed to a main and an auxiliary closure, with a flanged piercing member extending through hole in the auxiliary closure and movable with the auxiliary closure to displace a sealing disc carried by the main closure. 7

In copending application Ser. No. 791,428, filed December 12, 1947, the claims are directed to a tubular disc displacing member wherein the tube is provided with a flange which is arranged within the auxiliary closure.

From the foregoing description it will be apparent that I have invented a novel closure device which can be economicalliy manufactured and which is highly efiicient for its intended use.

Having thus described my invention, I claim:

A closure device comprising a main body portion and an auxiliary flexible outer closure portion, said main body portion having a portion adapted to engage the neck of a bottle, said body portion having a sleeve portion adapted to fit within a bottle neck, said sleeve portion having an axial recess, a sealing disc closing said recess, a medicinal tablet in said recess, a cupped diaphragm closing the outer end of the recess, said auxiliary closure portion including a body having a skirt thereon, said outer closure portion having 15 4 an inwardly directed seal releasing stem adapted to engage and push said cupped diaphragm to disc releasing position.
